In order to balance this equation you need to count each element and how many of the individual elements are in the equation. _H2+N2=2 NH3 You multiply the 2 (Which is the coefficient) by the 3 (which is the subscript) This would equal 6 which indicated there are 6 hydrogen atoms on the right side so the left side should also have 6 hydrogen atoms
The missing coefficient on the left side must multiple the 2 to become 6 hydrogen Answer=3
Answer: According to Moseley, similar properties recur periodically when elements are arranged according to increasing atomic number. Atomic numbers, NOT weights, determine the factor of chemical properties.
Mendeleev realized that the physical and chemical properties of elements were related to their atomic mass in a "periodic" way, and arranged them so that groups of elements with similar properties fell into vertical columns in his table
Electron is the correct answer :D
Answer:
Not necessarily
Explanation:
In the event of incresing the temprature it is not necessary that the solubility will increase always. Solubility of solids increases but solubility of gases dectreases on increases the temprature.
In solid solubility may remain unchange on increasing the temprature. This happens due to the fact that on increasing the temprature the mobility of substances increases due to thus the solubility increases.
Answer:Upon analysis of the results hypothesis can be rejected or modified but you can never be proven to be correct 100% of the time
Explanation:
For example relativity has been tested many times so it is generally excepted as true but there could be an instance which has not been encountered where it is not true
